LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 617,554, dated January10, 1899. A Application ined July 1s, i897. serial No. 644,464. (Nomodem' Y f .To all whom it may concern:

Be it known that LWILLIAM H. BIeELow, a citizen of the United States,residing-at Tarpon Springs, in the county of Hillsborough, in the Stateof Florida, have invented certain new and useful Improvements inLubricators, of which the following is a specification, reference beinghad to the accompanying drawings.

My invention relates'to lubricators whichy are designed to supply alliquid lubricant to the working parts of-a machine and is of that classin which the lubricant is conveyed to a plurality of journal-bearingsfrom a single point.

The objects of my invention are, first, to so divide the lubricant thateach and every journal-bearing shall receive a portion of it, and,second, to so apportion the lubricant that journal-bearings of differentdimensions and requirements as to lubricant shall receive different andsuitable portions of it.

In the accompanying drawings, Figure lis a central vertical section of alubricator embodying my invention. Fig. 2 is a horizontal section of thelubricator on the line y y of Fig. 3 is a central vertical section ofanother lnbricator embodying my invention in a modified form. Fig. 4 isa horizontal section of the lubricator shown in Fig. 3l on the line oc.Fig. 5 is a top plan view, sectional through guide F of Fig. 3, of thetable H in a modified form. y Like letters denote corresponding parts.In the drawings, G is a receptacle for the lubricant, preferably made ofglass, (indicated by G,) and G is acylindrical base integral with it.

N is a cap covering the opening at which the receptacle is filled. i

B is a bracket-supporting cup. At the bottom of the cup and integralwith it are pockets A A and ducts D D.

C C are conduits which conduct the liquid from the ducts to thejournal-bearings.

His a dome upon which the lubricant is delivered from the receptacle andwhose hori- -zontal base circumference overhangs the pockets A A.

M is a standard integral with H, which moves vertically within the guideI.

K is a valve-seat.

S is a spiral spring which closes the valve, and R is a cord u'pon whicha downward pull opens the valve. a a' a are radial partitions betweenthe pockets.

In Fig. 1, H is a hollow cone with a vertical axis and horizontal base.The apex and upper part of this cone in the valve-seat K' forms thesupply-valve. The apex of the cone is always (whether the valve is openor closed) above the port of the valve and always wholly within thevalve-seat K.

Referring to Figs. l and 2, it is'apparent that thepockets when taken inconnection with the overhanging base circumference of H snbtend unequalsegments of said circumference and therefore receive unequal portions ofthe drip from I-I, and that pockets which subtend the greater segmentsreceive the greater portions of the lubricant, and

these greater portions are conveyed through ducts and conduits tojournal-bearings requiring the larger allowances, While the receiptsfrom pockets which subtend lesser segments will go to bearings whichrequire less lubricant. It is obvious that in this manner with accurateconstruction each modicum of--- fe.``

when it is being delivered upon the dome H to assume a pipe shape, whosehorizontal cross-section is annular. Instead of a cylinder a frustum ofa cone or other form may be putin the center of the valve-port, theobject being to shape the escaping lubricant into annular form inhorizontal cross-see' F, K, V, H, and M have one and they tion.

same vertical axis. -In the lubricator shown in Fig. 3 a lever T isemployed to open the supply-valve, and in the bracket at T are pinholesadapted to receive a pin, and thereby graduate the opening of thesupply-valve.

In the lubricator shown in Figs. 3 and 4 each of the pockets subtend anequal segment of the overhanging base circumference of the dome H, andtherefore each receives an equal share of the modicum of liquid whendelivered through the valve upon II, and, through its own proper ductand conduit, conveys it to its allotted bearing. In this construction ifan unequal and larger portion is desired it can be secured by joiningthe receipts of two or more pockets, as shown in Fig. 3, where two ductslead into one conduit.

For the dome in Fig. 3 either a section of a hollovr cone or section ofa hollour spheroid may be substituted for the section of a hollowsphere.

For the dome in Fig. l either a section of a hollow sphere or section ofa hollow spheroid may be substituted for the section of a hollow cone,and the dome I-I in Fig. l, or either of its substitutes, may beprovided with a cylindrical guide like F in Fig. 3.

In Fig. 5 the dome is concaved near the base and the number of valleysare separated from each other by ridges along meridian lines a a d, atwhich points ridges or partitions are located. These valleys serve asconduits to pockets which have ducts D, and these pockets and ducts areintegral with the dome II and not integral with the bracketcup, as shownin the other drawings.

It is manifest that the lubricators shown in Figs. l and' 3 may be somodified in their construction that the partitions which divide thelubricant at or near the base circumference of the dome II shall beintegral with said dome, and that the pockets also shall be integralwith the dome andas well the ducts, and these may be the preferableforms of my invention.

E shows the form which the lubricant assumes around about thecylindrical, guide F when the valve is opened, and the lubricant assumesa like annular form below the ports of the valves around about all thedomes shown in the drawings.

In the lubricator shown in Fig. l the extent of the opening of thesupply-valve is limited by the shoulder at the top of the guide I.

What I claim, and desire to secure by Letters yPatent of the UnitedStates, is-

l. In combination, the reservoir, having the supply-opening leadingtherefrom, the series of conduits, the dome having a valve portion,means for moving Jthe dome to open the valve and the spring forreturning the dome to a closed position.

2. In combination, the reservoir, the dome below the same having thecylindrical part F at its apex and the valve portionv V closingdownwardly, the said dome and valve being movable, and the conduits forreceiving the lubricant from the dome, the said cylindrical part Fpassing through the port leading from the reservoir, substantially asdescribed.
